Purpose. We describe in detail a relatively simple technique of fundus photography in human and rabbit eyes using a smartphone, an inexpensive app for the smartphone, and instruments that are readily available in an ophthalmic practice. Methods. Fundus images were captured with a smartphone and a 20D lens with or without a Koeppe lens. By using the coaxial light source of the phone, this system works as an indirect ophthalmoscope that creates a digital image of the fundus. The application whose software allows for independent control of focus, exposure, and light intensity during video filming was used. With this app, we recorded high-definition videos of the fundus and subsequently extracted high-quality, still images from the video clip. Results. The described technique of smartphone fundus photography was able to capture excellent high-quality fundus images in both children under anesthesia and in awake adults. Excellent images were acquired with the 20D lens alone in the clinic, and the addition of the Koeppe lens in the operating room resulted in the best quality images. Successful photodocumentation of rabbit fundus was achieved in control and experimental eyes. Conclusion. The currently described system was able to take consistently high-quality fundus photographs in patients and in animals using readily available instruments that are portable with simple power sources. It is relatively simple to master, is relatively inexpensive, and can take advantage of the expanding mobile-telephone networks for telemedicine.

“…Such devices may one day be capable of routinely monitoring ART or identifying latent HIV reservoirs. Smartphones utilizing mobile applications have been integrated with microfluidics and paper-based portable platforms for the quantification of target biomolecules [77,110,165–168], and we envision that future POC technologies will likely incorporate mobile technologies since they are portable, inexpensive, and have high processing capabilities. Another technology that is likely to become important in resource-limited settings is the creation of wearable/implantable sensors, which can be used for patient health status monitoring including blood parameters, body temperature, pressure, and pH of the bio-environment [169–174].…”

HIV is a major global epidemic that requires sophisticated clinical management. While there have been remarkable efforts to develop new strategies for detecting and treating HIV, it has been challenging to translate them into resource-limited settings. Significant research efforts have been recently devoted to developing point-of-care (POC) diagnostics that can monitor HIV viral load with high sensitivity by leveraging micro- and nano-scale technologies. These POC devices can be applied to monitoring antiretroviral therapy, early infant detection of HIV during mother-to-child transmission, and identification of latent HIV reservoirs. In this review, we discuss current challenges in HIV diagnosis and therapy in resource-limited settings and present emerging technologies that aim to solve these challenges using novel micro- and nanoscale solutions.

“…Other applications provide lists of important diseases that should not be missed, definitions and differential diagnoses, color–coded diagrams of retinal drawings, questionnaires for common ophthalmic diseases and summaries of outstanding randomized controlled trials in ophthalmology. [ 6 ] Several applications provide information on general medical conditions, including symptoms, diagnoses, differential diagnoses, pathogenesis and treatment options. The most popular of these are Medscape, Epocrates and UpToDate which prepare up to date information that is useful for performing evidence-based medicine.…”
